Redundant Appliance Sync
AirDefense provides a feature that allows you to synchronize the configuration on your primary and
secondary servers. There are two methods to accomplish this:
Manual Synchronization
Automatic Synchronization
The proper way to synchronize servers is to configure your primary server first and then synchronize
your secondary server with your primary server. All configuration settings are copied from your primary
server to your secondary server so that the two servers have the same configuration. Configuration
settings from the primary server will override any configuration settings on the secondary server.
How Synchronization Works
Synchronization will not work if there is no backup file or if there is a backup in progress.
On the standby server, during either scheduled or on-demand synchronization, the standby server
pulls the current backup from /usr/local/smx/backups on the primary server.
NEVER schedule a synchronization or perform an on-demand synchronization at the same time a
backup is occurring on the primary server.
NEVER start an on-demand backup while synchronizing servers.
The backup file is copied to /usr/local/smx/backups on the standby machine which brings up
two important points:
NEVER schedule a local, remote or on-demand backup on the standby machine. If you do, it will
overwrite the file transferred over from the primary server.
NEVER direct a backup from the primary server to /usr/local/smx/backups on a standby
server. This will prevent synchronization from working properly.
